Golf club head with multiple dimpled face

ABSTRACT

The present invention relates to a golf club head with a multiple dimpled face. The present invention provides golf club head having a neck  12  to which a club shaft is connected, a bottom sole  14 , a top edge  16 , and a face  18 , wherein the face  18  is provided with a number of dimples  20  in the form of circle.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a golf club head with a multipledimpled face, particularly to a golf club head of iron golf clubs orwood-type golf clubs having a improved face to enhance functions of golfclubs.

[0002] Generally, a golf club head of iron golf clubs or wood-type golfclubs provides with a number of at a face with which contacts thesurface of golf balls to prevent golf balls from slipping during impactwith golf balls, to stop golf balls on putting green without running, ifa golf club is an iron golf club, and to achieve back-spin of golfballs.

[0003] However, for many of professional golfers and amateur golfers,although there is a somewhat difference in terms of technical abilitybetween them, all that matters is a directional behavior and drivingdistance of balls struck by them. It is known that professional golfershave not any problems to control their driving distance of balls in theexisting golf course, but all of them do not satisfy to control thedirectional behavior of balls and the running of balls on putting green.

[0004] Furthermore, many of amateur golfers do not satisfy to controlthe directional behavior of balls in the fairway. In the directionalbehavior of balls, it includes three behaviors, that is, a straighttrajectory behavior from a stable swing and an ideal striking of sweetspot during impact with golf balls, a hook behavior from a prematurewinding of a closed club head due to an unstable setup of a golfer andfrom a sliding of golf balls during contact with a club face, and aslice behavior from an unstable setup of a golfer and from contactinggolf balls with an open club face.

[0005] Known golf club head has disadvantage that a club face isprovided with a number of horizontal grooves, so that, though the clubface having the horizontal grooves prevent a golf balls from slidingupwardly and downwardly and provide a spin to golf balls during impactwith golf balls, it is difficult to prevent the golf balls from slidingon right and left.

[0006] The golf balls will have good directional behavior when thegolfer attends to his best conditions of swing, when the golf ballsimpact at the sweet spot of face, and when the target and the face aresquared, otherwise the golf balls will have poor directional behavior.Particularly, when the target and the face are not squared, the golfballs slip on the face so that the golf balls will have poor directionalbehavior.

[0007] Further, it is difficult to effectively provide a spin to thegolf balls by means of the club face having only horizontal grooves. Toimprove directional behaviors such as the hook or the slice, an attemptis proposed to permit the weight of the club head to be distributed forgood directional behavior of golf balls. But as this attempt is littleeffective, the golf club to which this attempt is applied are not usedwidely. Further, in the case of the short iron(#7, #8 or #9 iron) clubsor wedge(pitching or sand wedge) clubs, because of having small loft,they have effects for stopping golf balls at the dropping site withoutrunning and achieving back-spin of golf balls, but in the case of themiddle or long iron clubs having large loft, the back-spin of golf ballsis decreased, so that the golf balls may often miss to drop on theputting green.

SUMMARY OF THE INVENTION

[0008] One object of the present invention is to overcome the abovementioned problems associated with the golf club head having horizontalgrooves at the face.

[0009] Another object of the present invention is to provide a golf clubhead of iron golf clubs or wood-type golf clubs having a improved faceto enhance functions of golf clubs.

[0010] And another object of the present invention is to provide a golfclub head to allow a directional behavior of golf balls to be good. Ifone can obtain perfect technique in golf swing, one may play golf ofhigh level with the golf club of the present invention.

[0011] According to the present invention, the present inventionprovides a golf club head having a neck to which a club shaft isconnected, a bottom sole, a top edge, and a face, wherein the face isprovided with a number of dimples in the form of circle.

[0012] Preferably, the rows of dimples are arranged diagonally in theface in reference to the bottom sole line, such that the dimples arestaggered upwardly and downwardly and spaced at regular intervals. Theface may be provided with a number of dimples, such that the row ofdimples are arranged horizontally in reference to the bottom sole line.The dimples may be a form of a ellipse.

[0013] The present invention will be better understood from thefollowing detailed description taken with the accompanying drawings, inwhich:

DETAILED DESCRIPTION

[0021] Referring to FIG. 1 and FIG. 3a, the illustrated golf club head10, in the form of an iron golf club, has a neck 12 to which a clubshaft(not shown) is connected, a bottom sole 14, a top edge 16, and aface 18. The face 18 is provided with a number of dimples 20 accordingto the present invention. The rows of dimples 20 are arranged diagonallyin the face 18 in reference to the bottom sole line, such that thedimples are staggered upwardly and downwardly and spaced at regularintervals.

[0022] The golf club head 10 having the face 18 in which a number ofdimples 20 are formed according to the present invention may effectivelyprevent a golf balls from sliding in every direction. Specially, thegolf club head according to the present invention provides a reductionof sliding phenomenon between the face and golf balls, such that theface according to the present invention will prevent the golf balls fromsliding at the dimples g when the edge of dimples of the face contactsthe portion adjacent of dimples of golf balls.

[0023] The face formed with a number of dimples may provide a desiredimpact feel to golfer due to the reduction of sliding of golf ballsduring impact with golf balls and create a good directional behavior ofgolf balls.

[0024] And when the golf balls is struck by the face, the golf ballscould be stayed at the face on comparatively long time due to theincreasing of contact surface between the balls and the face, so that adirectional behavior of golf balls is improved and, in the case of themiddle or long iron, the spin effect of golf balls is increasinglyimproved.

[0025]FIG. 3b shows the another embodiment of golf club head 10according to the present invention, which is provided with a number ofdimples 20 at the face 18 such that the row of dimples are arrangedhorizontally in reference to the bottom sole line.

[0026] The embodiment of the present invention shows a superior spineffect of golf balls than that of former embodiment, but shows theexperimental results of reduction of the directional behavior.

[0027]FIG. 4 shows a further embodiment adapted to an iron club in whicha number of dimples 20′ in the form of ellipse are formed at the face.

[0028]FIG. 5 shows a embodiment adapted to a wood type golf club inwhich a number of dimples 20 are formed at the face 18 such that therows of dimples 20 are arranged diagonally in the face 18 in referenceto the bottom sole line, such that the dimples are staggered upwardlyand downwardly and spaced at regular intervals, similar to the golf clubhead shown in FIG. 3a.

[0029] The inventor has obtained the experimental results of differencebetween the iron club of the present invention and the existing ironclub in term of the directional behavior of golf balls and the spineffect. Also, The inventor has obtained the experimental results thatthe golf balls struck by the existing iron club got out of a lineextending on the target by about 20 yards when the golf balls droppedafter flight of about 150 yards. But the golf balls struck by the ironclub of the present invention got out of a line extending on the targetno less than about 10 yards in hook or slice.

[0030] Furthermore, The inventor has obtained the experimental resultsthat the golf balls struck by the iron club of the present inventionstopped on putting green without a conspicuous running, if a golf clubis an iron golf club. But the golf balls struck by the existing ironclub have run remarkable distance from the dropping site.

 2. Golf club head according to claim 1, wherein the rows ofdimples 20 are arranged diagonally in the face 18 in reference to thebottom sole line, such that the dimples are staggered upwardly anddownwardly and spaced at regular intervals.
